I have a stock block and about 8.7:1.A block can split at anytime and there is no magical number.I have mine detuned to help avoid that.But i have freinds that are making 550 hp and it last for years and others making 450 hp that last a few trips to the strip.A main girdle just helps in keeping the parts in a pile if the block does split. They also make a valley girdle, but havent seen that be the end all fix yet.I have run up to 15 psi on my block but keep it at about 10psi now.

When i rebuilt my c4, i added a couple more clutches,76' Mustang II converter(2800 stall) and raised the line pressure.I used that trans with nitrous for years and then sold it to a friend, so now its about 15+years old and he's using behind a 347 stroker.
I love my broader performance pro tree transbrake vb.

PA Automatics are good, at least my complete one was so I'd assume their valve bodies are good also. Had tons of passes low 10's high 9's and several low 9's and never had it apart. 2-3 shift was starting to get strained by my 1000hp so I sold it to a friend for his 600hp deal and back to shifting perfect again.
I know 600hp deals they will last a long ass time if done right.

well I was looking over my car before I headed over to irwindale and noticed that I have a lot of dent marks where my drive shaft meets the rear end. I checked to make sure all the Ubolts and driveshaft bolts were tight. Everything checked ok. I have noticed that in the past few days my upper end power is a lot stronger but my low end felt a little sluggish and I kept hearing a banging/grinding noise from the rear. This was after taking everyones advice and changing the timing and fueling a tad. So ive came to the conclusion that I fixed the lack of power but now im going to need a set of traction bars hahahaha. But ya im getting quite a bit of wheel hop and loss of traction, the rear reaaaally has to be twisting hard to bring the snout of the rear end that high into the tunnel wall. You guys think I should run it tonight or will I snap something hahaha? and also is there really a big difference between some cheaper slapper bars and caltracs? I know im going to need new springs and traction bars soon but I don't really feel like dropping 340$ on caltracs, thanks for the help guys!!

how low is your car? Is your pinion angle set correctly??
And there is a big difference in Caltracs and slapper bars. They both work, but one works better.

So I got back and my best time was 8.4 @ 81.38 I only got 2 runs and this was my first time on the strip ever, the 60 ft was 1.889 so I didn't to bad with stock suspension and a ton of wheel hop but the only issue was on the 3rd run I blew the tranny... 3rd gear is gon, I was planning on rebuilding it soon enough but does anyone know a good performance rebuild kit that will last 500+ hp?

Check out broader performance. There is a link above. I used a lot of their parts in mine and it is hanging in at over 650rwhp...knock on wood.
